Question

when a loop of wire is in a magnetic field, which induces acurrent in the wire, how do u figure out the:
1) direction of the magnetic flux () in thesystem 2) direction of the resulting induced magneticfield within the loop 3) direction of the current induced in thewire the magnetic flux is really confusing me. when a loop of wire is in a magnetic field, which induces acurrent in the wire, how do u figure out the:

Explanation / Answer

Given :          when aloop of wire is in a magnetic field, which induces a current in thewire, (a)  Direction of magnetic flux is always in thedirection of the field. (b)  Direction of Induced emf opposes the causethat produced it . Hence it in opposite direction to thefield. (c)   Direction of current is also in oppositedirection to the field. Hope this helps u!
